Puzzle boxes,
for one sitting.

Stand-alone puzzle boxes — no series to follow, no characters to remember, just a deck of cards, a tricky lock and an evening to crack it. Solo or small groups. Posted worldwide.

How a puzzle box works

A single sitting, a single answer.

Every box contains a deck of stand-alone puzzle cards. Each one can be solved on its own — pass them around, divide and conquer — but their answers feed into one final solution. Sealed solutions stay tucked away until you're ready to check your work. No companion website, no app, just paper and pencil.
